E LEGTRIO 'WINDOW-CLOSING-` DVIGE.

Application led September 20, 1926. Serial No. 136,537. o

My invention relates to electric window closing'devices and has a particular reference tov electromagnetic locking devices adapted to keep window panels in an open position until the magnets of said devices are energized by the electric current, when said locking devices re/lease said panels to be closed by their own weight or by counterweights.

. The object of my invention is to provide an electromagnetic device for the above purpose which could be conveniently oper-l ated by a push button' or by an automatic electric switch actuated by rain. With my mechanism it is possible to have all win dows in a house to be controlled by such electromagnetic devices connected with a rain switch, so that as soon as' rain starts, all these windows which remained open, will be immediately' and automatically closed thereby preventing the rain froin getting inside of the house.

l also ,provide my device with -a means whereby the electric circuit is automatically interrupted after the switch has worked once thereby preventing the waste of electric energy.

My invention is more fully described in the accompanying specification and drawing in which- Fig.' 1 is an elevation of my device in an operative position, supporting the window panel in a raised position, lli`ig. `2 is a diagrammatic view showing arrangement of my devices' on a window with *two movable panels and with automatic and manual switches, and Fig. 3 is an elevation of my device in an inoperative position.

My device consists of a housing 1 in which a magnet-2 is mounted.l An armature 3 is pivotally supported on a lug4 on'said housf lng with a pin 5. A spring G-,keeps the Aarmature away from the magnet when the latter is not energized and restlng against arest block?.4

A bar* 8 rot-atively supported on a bracket 9. with a'pin One end of said bar is providedwlth lugsfll with a pin 12 von which is pivoted a locking .arm 1.3.

, spring 14 tends tokeep this locking arm in alignment vwith the bar 8,- the tail end of this" arm resting against the central vcurved portion of the bar 8. A spring tends to turn the bar 8 with 'the armTI'S into an operating position, as shown in Fig. 1,

with the end `of the bar 8 locked againstthe' A Mina armature 3, so-that the arm 13 can support the weight of a window panel 17 by engaging one of the notches 18 of a metal strip 19 attached to .the edge of the panel 17.

The bar 8 has a piece of insulation 20 attached to the rear side of its front end and with this insulation it presses against contact springs 21 and 22 bringing them. together. These contact springs are interposed in the winding ofthe magnet 2, so that the circuit through the winding is interrupted when these contact springs are separated.

rlhe frame or housing 1 has lugs 23 for attaching it to the wall or wind-ow sash 24. Leads or wires 25 and 26 connect the mag` net 2 with aI push button or' switch 27 through a battery or similar source of electric current 28. instead of a switch 27 or parallel with it an automaticrain switch 29l may be used, operated bya lever 30 with a cup 31 adapted .to collect rain drops. The lever is pivoted ih the central point, so that 'the Weight of water collect-ed in the cup 31.

will cause its turning and closing the circuit. The-,operationJ of my device is.4 as follows. When it is desired to open the window the i' panel 17 is raised. allowing the arm 8 to turn until its rear end catches behind the lower end of `the armature 3 in which position it becomes locked. The lug 13 will catch one .of the notches 18 and will support lthe panel 17 in a fposition desired. The contact, springs 21 and 22 will be brought together making possible the closing of thecircuit by a switch. y The notched bar 19 may be of any length up to the full height of the panel 17vand it is attached with screws 32.

The panel 17 may be of an ordinary construction and provided with counterweights 33 on ropes-34 suspended on sheaves 35.

These counterweights,r however, are made light, so that the panel, when left without support, will drop down and close the window.

The arm 13 does not interfere with opening of the window or raising of the panel 17, being easily deected against the spring F positicn shown with dotted lines in 'he upper panel 36 is provided with extra heavy counterweights (not shown) so that it slides up and closes 'the window if left without Supporting or retaining device. The locking device for this panel is placed accordingly in an invertedpposltion (shown with dotted lines in Fig. 2), so that the lug 13 prevents the Window panel 36 from moving up.

As soon as the electric circuit is closed,

the magnet 2 att-racts the armature 3 thereby' arated, so that the current will not..be used if it starts to rain again or the sWitch 27 and 29 is closed.

VIt is evident that one switch, automatic or manual, can control any number of Windows.

Important advantages of. my device. are that it can retain the Window in any position and releases it automatically When the rain starts, also that no current is used after. the Window has been closed.

I (claim as my invention:

l. In a Window/closing device, the combination with a magnet of anarmature in a cooperative relation with said magnet, an arm pivotally supported in a cooperative relation with said armature and adapted to vsupport the Window panel in an open position, said arm being further adapted to be locked in an operative position with the Window panel open by said armature and .to be released When said magnet is energized.

2. In a Window closing device, thecombination with a housing, a magnet in said housing, an armature pivotally supported in said housing and adapted to be operated by said magnet, an arm rotatively mounted in said housing and adapted to engage the Window panel in an open position and adapted to be locked by said armature) said armature being adaptedto release-said arm when said magnet is, energized, .and means to render said magnet inoperative whenl said Y Window is closed.

'i housing being, adapted to be attached to the l v3. In a window closingfdevice, the comnbination Witha hou/singoffa magnet vin said v housing, an armature V pivotallysupported in said housing, an armipiv'otallySupportedin said housing, a pivotal bar on said-arm, s'ald Window frame, the window panel being provided With a plurality of notches, said pivoted bar being adapted to engagevone of said notches When said Window panel is placed in an open position, said armature being adapted to lock said arm with said pivotal Abar in an operative position vinanengagement with said-window. panel, said pivoted bar being adaptedV to swing out of the Way when said Windoivpanel is being'` moved into the openposition, and means to retrieve said pivotal bar into its operating4 osition.` j .f
